Answer:
Human microbiome
Explanation:
The microbiota that aggregates in the human tissues including placenta, skin, lungs, saliva, and seminal fluid is the human microbiome. The microbiota can be virus, bacteria, fungi and protists.
The microbiome present in the human gut helps in digestion and also provides immunity. Microbiomes can be healthy or unhealthy and an imbalance of both can lead to weight gain, high cholesterol and blood sugar. These are the ecological communities that includes symbiotic, commensal and pathogenic microorganisms.
Answer;
Glucose
The nutrient that can be used to produce energy in the absence of oxygen is glucose.
Explanation;
Production of energy without using glucose is called anaerobic respiration. During this type of respiration less energy is released than the case of aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt, which is the amount of oxygen needed to break lactic acid to carbon dioxide and water.
